Methods and systems for providing notifications to users of a social networking service

ABSTRACT

A method of providing notifications to users of a social networking service includes determining a user intent associated with a post from a user on the social networking service, based at least in part on content of the post. The method further includes generating a first notification of the user intent associated with the post and selecting a plurality of users of the social networking service to receive the first notification. The method further includes providing the first notification to the plurality of users, and after providing the first notification to the plurality of users: (1) receiving one or more responses to the first notification from one or more users of the plurality of users, the one or more responses including information responsive to the first notification, and (2) providing the information responsive to the first notification to the user.

TECHNICAL FIELD

This relates generally to providing notifications, including but not limited to providing notifications to users of a social networking service.

BACKGROUND

Social networking services provide a convenient means for users to share information. Certain users may possess information (e.g., information such as a review of a local business or tourist attraction) that other users may find helpful or useful. However, connecting users that possess useful information with other users seeking the useful information can be a challenging process for the social networking services.

SUMMARY

Accordingly, there is a need for methods and systems for notifying users of a social networking service that possess information sought by other users. Determining a user intent associated with a post from a user of the social networking service, generating a first notification of the user intent associated with the post, and providing the first notification to a plurality of users (e.g., users that may possess useful information associated with the user intent) can improve the sharing of useful information on the social networking service. Such methods and systems provide the social networking service with processes to provide information (e.g., relevant, useful information) responsive to the first notification to the user.

In accordance with some embodiments, a method is performed at a server system having one or more processors and memory storing instructions for execution by the processors. The method includes determining a user intent associated with a post from a user on a social networking service, based at least in part on content of the post. The method further includes generating a first notification of the user intent associated with the post and selecting a plurality of users of the social networking service to receive the first notification. The method further includes providing the first notification to the plurality of users, and after providing the first notification to the plurality of users: (1) receiving one or more responses to the first notification from one or more users of the plurality of users, the one or more responses including information responsive to the first notification, and (2) providing the information responsive to the first notification to the user.

In accordance with some embodiments, a server system includes one or more processors/cores and memory storing one or more programs configured to be executed by the one or more processors/cores. The one or more programs include instructions for performing the operations of the method described above. In accordance with some embodiments, a non-transitory computer-readable storage medium has stored therein instructions that, when executed by one or more processors/cores of a server system, cause the server system to perform the operations of the method described above.

FIG. 1 is a block diagram illustrating an exemplary network architecture of a social network in accordance with some embodiments. The network architecture 100 includes a number of client devices (also called “client systems,” “client computers,” or “clients”) 104-1, 104-2, . . . 104-n communicably connected to a social networking system 108 by one or more networks 106.

In some embodiments, the client devices 104-1, 104-2, . . . 104-n are computing devices such as smart watches, personal digital assistants, portable media players, smart phones, tablet computers, 2D gaming devices, 3D gaming devices, virtual reality devices, laptop computers, desktop computers, televisions with one or more processors embedded therein or coupled thereto, in-vehicle information systems (e.g., an in-car computer system that provides navigation, entertainment, and/or other information), or other appropriate computing devices that can be used to communicate with an electronic social networking system and other computing devices (e.g., via the electronic social networking system). In some embodiments, the social networking system 108 is a single computing device such as a computer server, while in other embodiments, the social networking system 108 is implemented by multiple computing devices working together to perform the actions of a server system (e.g., cloud computing). In some embodiments, the network 106 is a public communication network (e.g., the Internet or a cellular data network), a private communications network (e.g., private LAN or leased lines), or a combination of such communication networks.

Users 102-1, 102-2, . . . 102-n employ the client devices 104-1, 104-2, . . . 104-n to access the social networking system 108 and to participate in a social networking service. For example, one or more of the client devices 104-1, 104-2, . . . 104-n execute web browser applications that can be used to access the social networking service. As another example, one or more of the client devices 104-1, 104-2, . . . 104-n execute software applications that are specific to the one or more social networks (e.g., social networking “apps”, such as a Facebook social networking application, a messaging application, etc.).

Users interacting with the client devices 104-1, 104-2, . . . 104-n can participate in the social networking service provided by the social networking system 108 by providing and/or consuming (e.g., posting, writing, viewing, publishing, broadcasting, promoting, recommending, sharing) information, such as text comments (e.g., statuses, updates, announcements, replies, location “checks-in,” private/group messages), digital content (e.g., photos (i.e., images), videos, audio files, links, documents), and/or other electronic content. In some embodiments, users provide information to a page, group, message board, feed, and/or user profile of a social networking service provided by the social networking system 108. Users of the social networking service can also annotate information posted by other users of the social networking service (e.g., endorsing or “liking” a posting of another user, commenting on a posting by another user, or sharing a posting of another user).

In some embodiments, information can be posted on a user's behalf by systems and/or services external to the social network or the social networking system 108. For example, the user may post a review of a movie to a movie review website, and with proper permissions that website may cross-post the review to the social network on the user's behalf. In another example, a software application executing on a mobile client device, with proper permissions, may use a global navigation satellite system (GNSS) (e.g., global positioning system (GPS), GLONASS, etc.) or other geo-location capabilities (e.g., Wi-Fi or hybrid positioning systems) to determine the user's location and update the social network with the user's location (e.g., “At Home,” “At Work,” “In San Francisco, Calif.,” etc.), and/or update the social network with information derived from and/or based on the user's location. Users interacting with the client devices 104-1, 104-2, . . . 104-n can also use the social network provided by the social networking system 108 to define groups of users. Users interacting with the client devices 104-1, 104-2, . . . 104-n can also use the social network provided by the social networking system 108 to communicate (e.g., using a messaging application or built-in feature) and collaborate with each other.

In some embodiments, the network architecture 100 may also include third-party servers (not shown). In some embodiments, third-party servers are associated with third-party service providers that provide services and/or features to users of a network.

FIG. 2A is a block diagram illustrating an exemplary server system 200 in accordance with some embodiments. In some embodiments, the server system 200 is an example of a social networking system 108 (FIG. 1). The server system 200 typically includes one or more processing units (processors or cores) 202, one or more network or other communications interfaces 204, memory 206, and one or more communication buses 208 for interconnecting these components.

In some embodiments, memory 206 or the computer readable storage medium of memory 206 stores the following programs, modules, and data structures, or a subset or superset thereof:

-   -   an operating system 210 that includes procedures for handling         various basic system services and for performing         hardware-dependent tasks;     -   a network communication module 212 that is used for connecting         server system 200 (e.g., social networking system 108, FIG. 1)         to other computers (e.g., client devices 104-1, 104-2, . . .         104-n, and/or third party servers) via the one or more         communication network interfaces 204 (wired or wireless) and one         or more communication networks, such as the Internet, cellular         telephone networks, mobile data networks, other wide area         networks, local area networks, metropolitan area networks, and         so on;     -   a server database 214 for storing data associated with the         social networking service, such as:         -   entity information 216, such as user information 218, which             includes content items (e.g., images, videos, etc.) and             other user information (e.g., age of user, sex of the user,             etc.);         -   connection information 220;         -   user content 222; and         -   intent log 224;     -   text analyzing module 226 that operates upon text provided by         users of the social networking service (e.g., text in posts,         responses, etc.); and     -   a social networking server module 228 for providing social         networking services and related features (e.g., in conjunction         with social networking client module 280 on the client device         240, FIG. 2B), which includes:         -   a login module 230 for logging a user 102 at a client device             104 into the social networking system 108; and         -   a notification generator module 232 for generating a             notification (e.g., a first notification) based on a post             from a user 102-1, providing the notification to other users             102-2 . . . 102-n, and providing received responses (or             information contained therein) to the user 102-1, which             includes:             -   a relevance module 234 for determining a degree of                 relevance of received responses to the post from the                 user;             -   a selection module 236 for selecting users to receive                 the notification; and             -   a notification compiler module 238 for compiling the                 received responses and presenting one or more of the                 received responses (or information contained therein) to                 the user 102.

The server database 214 stores data associated with the server system 200 in one or more types of databases, such as text, graph, dimensional, flat, hierarchical, network, object-oriented, relational, and/or XML databases.

In some embodiments, the server database 214 includes a graph database, with entity information 216 represented as nodes in the graph database and connection information 220 represented as edges in the graph database. The graph database includes a plurality of nodes, as well as a plurality of edges that define connections between corresponding nodes. In some embodiments, the nodes and/or edges themselves are data objects that include the identifiers, attributes, and information for their corresponding entities, some of which are rendered at clients 104 on corresponding profile pages or other pages in the social networking service. In some embodiments, the nodes also include pointers or references to other objects, data structures, or resources for use in rendering content in conjunction with the rendering of the pages corresponding to the respective nodes at clients 104.

Entity information 216 includes user information 218, such as pictures associated with the user (e.g., images where the user has been tagged or otherwise identified), a plurality of icons, login information, payment credentials (e.g., credit-card or debit-card information, bank information, etc. for conducting financial transactions through the social networking service), privacy and other preferences, biographical data, and the like. In some embodiments, for a given user, the user information 218 includes the user's name, profile picture, a plurality of icons, contact information, birth date, sex, marital status, family status, employment, education background, preferences, interests, and/or other demographic information. In some embodiments, the user information may include other information, such as likes and comments, associated with, for example, profile pictures of the user (or other photos of the user).

In some embodiments, entity information 216 includes information about a physical location (e.g., a restaurant, theater, landmark, city, state, or country), real or intellectual property (e.g., a sculpture, painting, movie, game, song, idea/concept, photograph, or written work), a business, a group of people, and/or a group of businesses. In some embodiments, entity information 216 includes information about a resource, such as an audio file, a video file, a digital photo, a text file, a structured document (e.g., web page), or an application. For example, entity information 216 may include a location tag (e.g., Palo Alto, Calif., USA) for one or more digital photos. In some embodiments, the resource is located in the social networking system 108 (e.g., in content 222) or on an external server, such as a third-party server (not shown).

In some embodiments, connection information 220 includes information about the relationships between entities in server database 214. In some embodiments, connection information 220 includes information about edges that connect pairs of nodes in a graph database. In some embodiments, an edge connecting a pair of nodes represents a relationship between the pair of nodes (e.g., also referred to herein as a contact).

In some embodiments, an edge includes or represents one or more data objects or attributes that correspond to the relationship between a pair of nodes. For example, when a first user indicates that a second user is a “friend” of the first user, the social networking system 108 may transmit a “friend request” to the second user. If the second user confirms the “friend request,” the social networking system 108 may create and store an edge connecting the first user's user node and the second user's user node in a graph database as connection information 220 that indicates that the first user and the second user are friends (also referred to herein as a direct connection). In some embodiments, connection information 220 represents a friendship, a family relationship, a business or employment relationship, a fan relationship, a follower relationship, a visitor relationship, a subscriber relationship, a superior/subordinate relationship, a reciprocal relationship, a non-reciprocal relationship, another suitable type of relationship, or two or more such relationships.

In some embodiments, an edge between a user node and another entity node represents connection information 220 about a particular action or activity performed by a user of the user node towards the other entity node. For example, a user may “like” or have “attended,” “played,” “listened,” “cooked,” “worked at,” “watched,” etc. the entity at the other node. The page in the social networking service that corresponds to the entity at the other node may include, for example, a selectable “like,” “check in,” “add to favorites,” etc. icon (e.g., an affordance). After the user clicks one of these icons, the social networking system 108 may create a “like” edge, “check in” edge, a “favorites” edge, etc. in response to the corresponding user action. As another example, the user may listen to a particular song using a particular application (e.g., an online music application). In this case, the social networking system 108 may create a “listened” edge and a “used” edge between the user node that corresponds to the user and the entity nodes that correspond to the song and the application, respectively, to indicate that the user listened to the song and used the application. In addition, the social networking system 108 may create a “played” edge between the entity nodes that correspond to the song and the application to indicate that the particular song was played by the particular application.

In some embodiments, content 222 includes text (e.g., ASCII, SGML, HTML), images (e.g., jpeg, tif and gif), graphics (e.g., vector-based or bitmap), audio, video (e.g., mpeg), other multimedia, and/or combinations thereof. In some embodiments, content 222 includes executable code (e.g., script for API calls), podcasts, links, and the like. In some embodiments, content 222 includes posts 240 (e.g., previous posts and/or current posts) along with associated notifications and responses.

In some embodiments, intent log 224 includes determined user intents associated with posts and responses. For example, the intent log 224 may include determined intents for respective posts.

FIG. 2B is a block diagram illustrating an exemplary client device 240, in accordance with some embodiments. The client device 240 is an example of the one or more client devices 104-1, 104-2, . . . 104-n (FIG. 1). The client device 240 typically includes one or more processing units (processors or cores) 242, one or more network or other communications interfaces 244, memory 246, and one or more communication buses 248 for interconnecting these components. The communication buses 248 optionally include circuitry (sometimes called a chipset) that interconnects and controls communications between system components. The client device 240 includes a user interface 250. The user interface 250 typically includes a display device 252. In some embodiments, the client device 240 includes inputs such as a keyboard, mouse, and/or other input buttons 256. Alternatively or in addition, in some embodiments, the display device 252 includes a touch-sensitive surface 254, in which case the display device 252 is a touch-sensitive display. In some embodiments, the touch-sensitive surface 254 is configured to detect various swipe gestures (e.g., continuous gestures in vertical and/or horizontal directions) and/or other gestures (e.g., single/double tap). In client devices that have a touch-sensitive display 252, a physical keyboard is optional (e.g., a soft keyboard may be displayed when keyboard entry is needed). The user interface 250 also includes an audio output device 258, such as speakers or an audio output connection connected to speakers, earphones, or headphones. Furthermore, some client devices 240 use a microphone and voice recognition to supplement or replace the keyboard. Optionally, the client device 240 includes an audio input device 260 (e.g., a microphone) to capture audio (e.g., speech from a user). Optionally, the client device 240 includes a location detection device 262, such as a GNSS (e.g., GPS, GLONASS, etc.) or other geo-location receiver, for determining the location of the client device 240.

In some embodiments, the home page may further include a news section 316. The news section 316 may include posts (e.g., post 318) made by users of the social networking service. The GUIs in these figures are used to illustrate the processes described below, including the method 400 (FIGS. 4A-4C). While FIGS. 3A-3F illustrate examples of GUIs, in other embodiments, one or more GUIs display user-interface elements in arrangements distinct from the embodiments of FIGS. 3A-3F. Moreover, one or more GUIs may lack feature(s) described above for ease of illustration.

FIGS. 4A-4C are flow diagrams illustrating a method of providing notifications to users of a social networking system, in accordance with some embodiments. The steps of the method 400 may be performed by a social networking system (e.g., social networking system 108, FIG. 1; server system 200, FIG. 2A). FIGS. 4A-4C correspond to instructions stored in a computer memory or computer readable storage medium (e.g., memory 206 of the server system 200). For example, the operations of method 400 are performed, at least in part, by a social networking server module (e.g., social networking server module 228, FIG. 2A) and a text analyzing module (e.g., text analyzing module 226, FIG. 2A). In some embodiments, the steps of the method 400 may be performed by any combination of client device (e.g., a client device 104, FIG. 1; client device 240, FIG. 2B) and the social networking system. To assist with describing the method 400, the method 400 will be described with reference to the exemplary GUIs illustrated in FIGS. 3A-3F.

In performing the method 400, the social networking system determines (402) a user intent associated with a post from a user (e.g., user 102-1, FIG. 1) on a social networking service, based at least in part on content of the post. In some embodiments, when determining the user intent associated with the post, the social networking system may identify (404) a request in the post for a recommendation (e.g., a recommendation for a restaurant). In some embodiments, when determining the user intent associated with the post, the social networking system may identify (406) an offer in the post (e.g., offering to sell a good or service). In some embodiments, the content of the post includes text in the post (e.g., words and/or phrases that compose the post). In some embodiments, the content of the post includes other information such as locational tags (e.g., the user may tag or otherwise identify his or her location in the post) and user tags (e.g., the user may tag or otherwise identify one or more contacts in the post).

In some embodiments, using a text analyzing program (e.g., text analyzing module 226, FIG. 2A), the social networking system may analyze the text in the post to determine the user intent associated with the post (e.g., analyze text in response to the user 102-1 selecting 322 post button 314, FIG. 3A). For example, referring to FIG. 3A, the social networking system may analyze question 320 posed by John Smith (e.g., user 102-1). As shown, the question 320 reads, “Does anyone know a good French restaurant in Palo Alto?” In some embodiments, the social networking system may use natural language processing to analyze the question 320. Those skilled in the art will appreciate that various text analyzing programs may be used to analyze the question 320.

In some embodiments, the text analyzing program may include a text analysis model. In some embodiments, the text analysis model may direct the social networking system to identify one or more locations in the text. For example, referring to FIG. 3A, the social networking system may identify that the text includes a location, Palo Alto. In some circumstances and situations, the identified location may potentially relate to two or more locations (e.g., Palo Alto, Calif. and Palo Alto, Tex.). In these circumstances or situations, the social networking system may further analyze the text and/or identify a current location of the client device (e.g., the client device 104-1 may be located in or near Palo Alto, Calif. when the post is made by the user) to resolve the ambiguity and determine the intended location. In addition, the social networking system may analyze previous posts made within a relevant time period by the user (e.g., the user 102-1 may have posted earlier in the day, “I love visiting California, it's my favorite state”) to determine the intended location.

In some embodiments, the text analysis model may direct the social networking system to identify one or more punctuation marks in the text. In this way, the social networking system may determine that a question (e.g., a request for a recommendation) is being made by the user (e.g., John Smith). For example, referring to FIG. 3A, the social networking system may identify that the question 320 includes a question mark.

In addition, in some embodiments, the text analysis model may direct the social networking system to identify one or more trigger words and/phrases in the text. In some embodiments, words and phrases such as “does anyone know,” “what is,” and other questioning terms may be a first category of trigger words and/or phrases associated with a request for a recommendation. In another example, words and phrases such as “does anyone want,” “what will you give me,” “I'm selling my,” and other terms likely to be included in an offer may be a second category of trigger words and/or phrases associated with an offer.

In some embodiments, when determining the user intent associated with the post (e.g., the question 320, FIG. 3A), the social networking system may compare (408) the content of the post with content of a plurality of previous posts (or simply a previous post) made by users of the social networking service (e.g., posts 240, FIG. 2A). Respective posts of the plurality of previous posts may have previously identified intents (410) (e.g., as stored in intent log 224, FIG. 2A). As such, the social networking system may match one or more respective posts of the plurality of previous posts with the post (e.g., the question 320, FIG. 3A) using the previously identified intents. For example, a previous post by a respective user of the social networking service may have been, “does anyone know a nice golf course near Salt Lake City?” In order to determine a user intent associated with the post, the social networking system may have asked, “would you like recommendations for golf courses near Salt Lake City?” In response to receiving an affirmative answer from the respective user, the social networking system may have logged that “does anyone know” may be associated with the user intent for a requested recommendation. Accordingly, referring to FIG. 3A, the social networking system may compare the question 320 to the previous post regarding golf courses to determine the user intent associated with the question 320 (e.g., seeking a recommendation for a restaurant).

In some embodiments, the text analysis model may include or access the plurality of previous posts and the previously identified intents. In addition, in accordance with a determination that a number of analyzed posts satisfy a threshold, the social networking system may update the text analysis model. For example, the updated text analysis model may include updated trigger words and/phrases. In addition, the updated text analysis model may include an updated plurality of previous posts made by users of the social networking service and updated identified intents for the updated plurality of previous posts.

In some embodiments, referring to FIG. 3A, in response to user selection 322 of post button 314, the social networking system may receive a request from the client device 104-1 for a notification feature provided by the social networking service. In response, the social networking system may generate a first notification (discussed below). In some embodiments, prior to the social networking system receiving the request, the social networking system (or the client device) may determine whether or not the user wants to launch the notification feature (e.g., present a yes-or-no question to the user in the application or the webpage on the client device 104-1).

The social networking system generates (412) a first notification of the user intent associated with the post (e.g., the question 320, FIG. 3A). In some embodiments, the social networking system may generate the first notification in response to receiving the request from the client device (e.g., the client device 104-1). In some embodiments, the social networking system may generate the first notification in accordance with a determination that the user intent associated with the post satisfies a user-intent threshold. For example, the social networking system may generate the first notification in accordance with a determination that the user intent associated with the post is an offer. In another example, the social networking system may generate the first notification in accordance with a determination that the user intent associated with the post is a request for a recommendation.

The social networking system selects (414) a plurality of users of the social networking service to receive the first notification. In some embodiments, when selecting the users to receive the first notification, the social networking system may determine (416) respective degrees of association between the user intent and users of the social networking service. For example, to determine a respective degree of association between the user intent and a respective user of the social networking service, the social networking system may determine a connection (e.g., an edge) between the user (e.g., a first node) and the respective user (e.g., a second node) of the social networking service in accordance with the determined user intent (e.g., user intent is for a French restaurant recommendation, FIG. 3A). In some embodiments, the connection between the first node and the second node may be an indirect connection. For example, the respective user (e.g., the second node) may have recently “checked in” to a location relevant to the user intent (e.g., French Restaurant X in Palo Alto, Calif.) (e.g., a third node). As such, the social networking system may log a connection (e.g., a first edge) between the respective user (e.g., the second node) and the location (e.g., French Restaurant X) (e.g., the third node). In addition, the social networking system may log (e.g., temporarily form) multiple connections (e.g., multiple second edges) between the user (e.g., the first node) and each potentially relevant location (e.g., each French restaurant in Palo Alto), including the third node. Consequently, the social networking system may log the indirect connection between the user (e.g., the first node) and the respective user (e.g., the second node) via French Restaurant X (e.g., the third node). Based on this connection, the social networking system may select the respective user to receive the first notification, because the respective user's action (e.g., “checking in” to French Restaurant X) creates a degree of association between the user intent and the respective user. The social networking system may perform the connection analysis for respective users of the social networking service. Moreover, “checking in” is simply one of many ways of creating an indirect connection. Edges and nodes are discussed in further detail above with reference to FIG. 2A.

In some embodiments, after determining the respective degrees of association between the user intent and one or more users of the social networking service, the social networking system may choose (418) users of the social networking service whose respective degrees of association satisfy a criterion. In some embodiments, the criterion may be based at least in part on location (e.g., the social networking system may connect nodes based on connection information associated with location). For example, referring to FIG. 3A, the social networking system may choose users who have visited, lived, and/or currently live in Palo Alto (and in some embodiments surrounding areas, e.g., a predetermined mile radius around Palo Alto). In some embodiments, as an alternative or in addition, the criterion may be based at least in part on activity (e.g., the social networking system may connect nodes based on connection information associated with activity). For example, the social networking system may choose users who have visited (e.g., “checked in,” “liked,” “favorited,” etc.) a location relevant to the user intent (e.g., a French restaurant in Palo Alto, and in some embodiments French restaurants in the surrounding areas). In some embodiments, as an alternative or in addition, the criterion may be based at least in part on time. For example, the social networking system may choose users who have visited Palo Alto within a threshold period of time and/or users who have visited a French restaurant in Palo Alto (and in some embodiments in the surrounding areas) within a threshold period of time. In some embodiments, the criterion is based at least on part on a combination of location, activity, and/or time. Moreover, the criterion may be based on other information (e.g., other portions of the connection information 220, FIG. 2A). Connection information 220 is discussed in further detail above with reference to FIG. 2A.

When choosing the users of the social networking service whose respective degrees of association satisfy the criterion, the social networking system may choose (420) users who are also contacts of the user and thus are directly connected to the user in the social networking service. Using the example from above, the social networking system may determine that an indirect connection exists between the user (e.g., the first node) and the respective user (e.g., the second node) via the French Restaurant X (e.g., the third node). Thereafter, the social networking system may also determine a direct connection (e.g., relationship) between the user (e.g., the first node) and the respective user (e.g., the second node). In this way, the social networking system may further limit a number of instances of the first notification provided. Moreover, the user may trust recommendations from contacts as opposed to recommendations from non-contacts.

In some embodiments, when selecting the users to receive the first notification, the social networking system may choose (422) users of the social networking service with respective degrees of association with the user that satisfy a criterion. To determine a respective degree of association with the user, the social networking system may determine a connection (e.g., an edge) between the user (e.g., a first node) and a respective user (e.g., a second node) of the social networking service. In some embodiments, the connection (e.g., the edge) may be a direct connection (e.g., an edge connecting a pair of nodes represents a relationship (e.g., friends, relatives, etc.) between the pair of nodes), such that the two users are contacts. In some embodiments, the criterion may be satisfied by direct connections. In some embodiments, the social networking system may choose (424) users who are contacts of the user. Edges and nodes are discussed in further detail above with reference to FIG. 2A.

In some embodiments, when selecting the users to receive the first notification, the social networking system may identify (426) a location of the user at the time of the post. In some circumstances, the social networking system may not determine a location of the user from the post (e.g., the user may post “Where can I find good French food.”). In these circumstances, the social networking system may determine the location of the user using other information. For example, the user may have “checked in” to the location (or near the location) prior to making the post (e.g., “checked in” 10 minutes prior to making the post). In another example, the social networking system may receive location information from the client device of the user (e.g., receive location information via a location detection device 262 of the client device 240, FIG. 2B).

Furthermore, when selecting the users to receive the first notification, the social networking system may choose (428) users of the social networking service with locations within a specified range of the identified location. For example, the social networking system may choose users who have visited, lived, and/or currently are visiting or live in the location (and in some embodiments surrounding areas). In some embodiments, the social networking system may limit the selection to users who have visited, lived, currently are visiting, and/or currently live in the location within a recent period of time (e.g., within the last year). In some embodiments, the period of time may vary depending on a nature of the location (e.g., the period of time may expand when the identified location is a foreign city).

In performing the method 400, the social networking system provides (430, FIG. 4B) the first notification to the plurality of users. For example, the social networking system may provide respective instances of the first notification to respective users of the plurality of users. Referring to FIG. 3B, the social networking system may provide User_17 with a respective instance of the first notification. In some embodiments, to view the first notification, the User_17 may interact with a display of client device 104-2 to select 324 a notification button 326 displayed on the display.

Furthermore, in some embodiments, the first notification may include a first portion and a second portion. In some embodiments, the first portion of the first notification may ask each of the plurality of selected users whether or not they want to participate (e.g., whether or not they want to provide a recommendation). For example, referring to FIG. 3C, the first portion 328 of the first notification 330 may relate to the question 320 (FIG. 3A) and may ask “Would you like to help John find a French restaurant in Palo Alto?” In another example, the first portion 328 of the first notification 330 may relate to a node (e.g., the third node) that forms an indirect connection between the user (e.g., the first node) and a respective user (e.g., the second node). For example, using the example from above, the respective user (e.g., the second node) may have recently “checked in” to the French Restaurant X. Accordingly, the first notification 330 may ask the respective user, “Would you like to recommend the French Restaurant X in Palo Alto you recently visited?” In some embodiments, the social networking system may skip the first portion 328 and simply present the second portion 338 of the first notification 330 to the respective user (FIG. 3D).

In some embodiments, in accordance with a determination that a respective user of the plurality of users declines to participate (e.g., selection of No-button 332, FIG. 3C), the social networking system may not present the second portion 338 of the first notification 330 to the respective user. However, in accordance with a determination that the respective user of the plurality of users accepts (selection 334 of Yes-button 336, FIG. 3C), the social networking system may present the second portion 338 of the first notification 330 to the respective user. Referring to FIG. 3D, User_17 may provide a recommendation 340 in the second portion 338 of the first notification 330. User_17 may interact with the display of client device 104-2 to select 342 a share button 344 displayed on the display.

After providing the first notification to the plurality of users, the social networking system receives (432) one or more responses to the first notification from one or more users of the plurality of users. The one or more responses may include information responsive to the first notification. The social networking system provides (434) the information responsive to the first notification to the user. In some embodiments, the information responsive to the first notification includes a response to the offer (436). In some embodiments, the information responsive to the first notification includes a recommendation (438). For example, referring to 3D, User_17 recommends French Restaurant X on University Avenue in Palo Alto. As such, the recommendation by User_17 includes information responsive to the first notification (i.e., John was seeking recommendations for French restaurant's in Palo Alto). In response to receiving the recommendation from the client device 104-2, the social networking system may provide the recommendation to the user. In some embodiments, the social networking system may provide (440) the one or more received responses to the user (e.g., the social networking system may not filter responses).

In some embodiments, prior to providing the information responsive to the first notification to the user, the social networking system may determine (442, FIG. 4C) relevance scores for the one or more received responses. The relevance scores indicate respective degrees of relevance of the one or more received responses to the user intent. The social networking system may determine relevance scores to filter out irrelevant (e.g., unhelpful) responses.

For example, when the user intent is for a restaurant recommendation, the social networking system may assign no score (or a zero score) to a received response that lacks a restaurant (i.e., no degree of relevance). In another example, the social networking system may assign a first score to a received response that includes a restaurant but does not address or conform to the user intent for the post (i.e., a first degree of relevance). For example, referring to FIG. 3A, the received response may say “too bad Palo Alto doesn't have a John's Steaks, I love that place.” Such as response does not address or conform to (i.e., is not relevant to) the user intent of the question 302 as the response does not actually provide the requested recommendation. In another example, the social networking system may assign a second score (e.g., higher than the first score) to a received response that includes a restaurant in a relevant geographic area (i.e., a second degree of relevance). For example, referring to FIG. 3D, User_17 recommends French Restaurant X located on University Avenue in Palo Alto. The social networking system may assign the second score to the received response as the received response addresses and conforms to the question 302 (FIG. 3A). In some embodiments, the social networking system may assign a third score (e.g., higher than the first and second scores) to a received response that is particularly relevant and/or useful (i.e., a third degree of relevance). For example, a received response from a respective user may include reviews of multiple French restaurants in Palo Alto.

In addition, the social networking system may determine (444) that the relevance scores for the one or more received responses satisfy a threshold. In some embodiments, the threshold may be associated with the respective degrees of relevance and/or the determined scores. For example, the social networking system may set the threshold such that responses with respective second degrees of relevance and above (or first degrees of relevance and above, or third degrees of relevance) satisfy the threshold.

In some embodiments, in accordance with determining that the relevance scores for received responses do not satisfy the threshold (444—No), the social networking system may discard (446) received responses that do not satisfy the threshold. For example, the social networking system may provide the first notification to a group of users of the social networking service. The social networking system may receive responses from at least some of the group. Out of those received responses, all or some may not be relevant to the question posed/asked by the user. For example, the social networking system may discard received responses of “have fun in Palo Alto!,” “French food is the best!,” and the like. Moreover, the social networking system may discard received responses with respective first degrees of relevance when the threshold is set to a second degree of relevance and above, or discard responses with respective first or second degrees of relevance when the threshold is set to a third degree of relevance.

In some embodiments, in accordance with determining that the relevance scores for the one or more received responses satisfy the threshold (444—Yes), the social networking system may provide (434) the information responsive to the first notification (i.e., the information in responses determined to be relevant to the user intent) to the user. For example, referring to FIG. 3E, the social networking system provides the response by User_17 to John Smith. When providing the response to John Smith, the social networking system may include the response by User_17 in a response section 346 of the post 348.

In some embodiments, the social networking system may determine (448, FIG. 4C) respective intents associated with the one or more received responses based at least in part on content of the one or more received responses (e.g., in a similar manner as for the user intent for the post). For example, referring to FIG. 3D, the social networking system may determine that the received response from User_17 is a recommendation by analyzing the text (e.g., analyzing the text for one or more restaurant names and for a relevant location). In some embodiments, the social networking system may compare content in a received response with connection information (e.g., connection information 220, FIG. 2A). For example, the social networking system may compare a restaurant name in a received response with one or more relevant pages on the social networking service. Referring to FIG. 3D, the social networking system may match the text, “French Restaurant X,” with a page (e.g., an account, a node) of French Restaurant X in the social networking service. In this way, the social networking system may determine that a given recommendation in a received response is relevant and valid. In another example, the social networking system may compare a restaurant name in a received response with a webpage distinct from the social networking service (e.g., the social networking system may perform a search on the World Wide Web).

Furthermore, the social networking system may determine whether the respective intents associated with the one or more received responses match the user intent. In some embodiments, in accordance with a determination that the respective intents associated with received responses do not match (e.g., do not relate to) the user intent, the social networking system may discard the received responses that do not match the user intent. In some embodiments, the social networking system may determine the respective intents associated with the one or more received responses when determining the relevance scores. For example, received responses with respective intents that do not match the user intent may receive a reduced score as compared to received responses with respective intents that match the user intent.

In some embodiments, in accordance with a determination that the respective intents associated with the one or more received responses match (e.g., relate to) the user intent, the social networking system may provide (434) the information responsive to the first notification to the user.

Furthermore, in some embodiments, the social networking system may generate (450) a second notification associated with the one or more received responses. The second notification includes indications of the respective intents associated with the one or more received responses. In some embodiments, the social networking system may generate the second notification in accordance with a determination that the respective intents associated with the one or more received responses match (e.g., relate to) the user intent. Alternatively or in addition, in some embodiments, the social networking system may generate the second notification in accordance with a determination that the relevance scores for the one or more received responses satisfy the threshold (444—Yes).

In some embodiments, when providing the information responsive to the first notification to the user, the social networking system may provide (452, FIG. 4B) the second notification to the user. For example, referring to FIG. 3E, the client device 104-1 may receive the second notification from the social networking system. In response to receiving the second notification, the client device 104-1 may signal reception of the second notification to the user 102-1 (i.e., John Smith) with an indicator 350 in the notification button 306. The user 102-1 may interact with a display (e.g., touch or click on) of the client device 104-1 to view the second notification (e.g., which includes the received response from User_17 or information from the received response from User_17). Although FIG. 3E shows a single notification in the notification button 306, a number in the indicator may reflect a number of received responses.

In some embodiments, the request in the post is for a recommendation in a geographic area. For example, referring to FIG. 3A, the question 320 requests a restaurant recommendation in Palo Alto, Calif., USA. In some embodiments, the recommendation in the information responsive to the first notification is specific to the geographic area. For example, referring to FIG. 3D, the response 340 by User_17 relates to a restaurant in Palo Alto.

In some embodiments, the social networking system may identify (454) a location for the recommendation in the information responsive to the first notification. In some embodiments, the social networking system may identify the location using connection information (e.g., connection information 220, FIG. 2A). For example, the social networking system may compare a restaurant name in a received response with one or more relevant pages on the social networking service. The social networking system may find a location associated with a page if the compare operation is successful (e.g., a match is found). In some embodiments, the social networking system may perform a search (e.g., on the World Wide Web) to identify the location for the recommendation.

In addition, the social networking system may generate (454) a map and add (456) a marker (e.g., marker 354, FIG. 3F) to the map (e.g., map 352, FIG. 3F) at the identified location. In some embodiments, the social networking system may add (458) a hyperlink to the marker. The hyperlink may be associated with the recommendation in the information responsive to the first notification. For example, the hyperlink may be for a page (e.g., a webpage) of the recommendation (e.g., recommendation 340, FIG. 3D) on the social networking service (e.g., the recommendation may be a node). In another example, the hyperlink may be for a webpage of the recommendation distinct from pages of the social networking service.

In some embodiments, the social networking system may provide (460) the map with the marker to the user. For example, referring to FIG. 3F, the social networking system may generate a map 352, add a marker 354 at the identified location, and provide the map 352 to the client device 104-1 for display. In some embodiments, the social networking system may add a plurality of markers to the map that are associated with respective received responses. Moreover, the social networking system may adjust a size of the map in accordance with identified locations for the respective received responses. For example, the social networking system may zoom out when the identified locations span a larger area (e.g., identified locations span multiple cities) as compared to a smaller area (e.g., a single city).
